Blow molding machines can be divided into three categories: extrusion blow molding machine, injection blow molding machine and special structure blow molding machine. Stretch blow molding machines can be assigned to each of the above categories. The extrusion blow molding machine is a combination of an extruder and a blow molding machine and a mold clamping mechanism, and is composed of an extruder and a parison die, an inflation device, a mold clamping mechanism, a parison thickness control system, and a transmission mechanism. The parison die is one of the important components that determine the quality of the blow molded product, typically a side feed die and a center feed die. The storage cylinder type blank die is often used for blow molding of large products. The storage tank has a minimum volume of 1kg and a maximum capacity of 240kg. The parison thickness control device is used to control the parison wall thickness, and the control point is up to 128 points, generally 20 to 30 points. The extrusion blow molding machine can produce hollow articles having a volume ranging from 2.5 ml to 104.
